The iFollow cameras focused on the younger members of our squad out in Portugal on Wednesday.
Sheffield's Regan Slater and Welsh U21s international Rhys Norrington-Davies are putting in the hard yards with more senior players, under Chris Wilder's watchful eye.
Regan said: "It is a bit too warm when you are training but it is nice to get away. I've worked hard through the summer and the aim is to try and get a shirt and keep it."
Rhys has a similar aspiration: "It's been a great trip so far, working with the first team, it is my first major trip away and hopefully I'll get a few minutes to show the gaffer what I've got."
Both could feature in Thursday evening's friendly with Maritimo.
